“…In the 1%, 2%, and 3% coconut coir fiber addition groups, the mean value was relatively not too high but there was an increase, although the value was not too large. The increase in tensile strength in the additional group of coconut coir fiber is due to the addition of fiber volume in each group and causes these fibers to be more able to transmit energy evenly and be able to accept greater tensile loads (Titani et al, 2018;Astika et al, 2013). This condition is in accordance with research Bale et al (2018) which states that the volume fraction of the fiber increases, indicating an increase in the load received by the fiber and the tensile strength.…”

“…Another study by Astika et al, (2013) on the mechanical properties of coco fiber as a reinforced polyester composite. In addition, this fiber reinforcement is also used in engineering by Titani et al (2018), namely the use of coconut fiber as a substitute for polyester composite fibers in aircraft structures. A similar study was also conducted by Prawesthi et al (2022b) on the use of ramie fiber and banana stems based on heat cured acrylic resin on impact and flexural strength.…”

Background: Acrylic denture base material has advantages such as good aesthetics, ease of repair, and affordable price, but this denture has mechanical properties, one of which is low tensile strength so fractures often occur during use. Utilization of natural fibers such as ramie (Boehmeria Nivea) and coconut coir (Coco Nucifera L) can be used as an alternative reinforcement for acrylic denture bases. Purpose: To determine the effect of adding ramie fiber and coconut coir fiber at different concentrations on the tensile strength of the acrylic denture base. Method: This study used a laboratory experimental method with a flat dumbell-shaped specimen with a size of 75 × 10 × 3 mm based on ISO 527-1 (2019). The specimens consisted of 42 plates which were divided into 7 groups, namely 6 specimens each group without fiber addition (control), with the addition of ramie fiber 1%, 2%, 3%, and the addition of coconut coir fiber 1%, 2%, 3%. Tensile strength testing using Universal Testing Machine (UTM), data were analyzed by One-way ANOVA test and Post Hoc LSD test. Result: The 3% ramie fiber addition group had the highest tensile strength (76.47 MPa), the 1% coconut coir fiber addition group had the lowest tensile strength (58.91 MPa). There was a significant difference in the results of the control group's tensile strength test and the addition of 3% ramie fiber and 1% coconut coir fiber (p-value < 0.05). Conclusion: The greater the concentration of ramie and coconut fiber additions, the higher the tensile strength value, although the tensile strength value in the coconut fiber addition group was lower than the control group and ramie fiber addition.

“…Komposit serat alam sudah banyak dimanfaatkan pada berbagai produk seperti otomotif [5]. Penelitian mengenai komposit serat alam juga sudah banyak dilakukan seperti pada serat kelapa [6], serat bambu [7], dan serat tebu [8]. Pada penelitian ini, serat sabut kelapa dipilih sebagai bahan yang akan digunakan karena sabut kelapa tersedia dalam jumlah besar, mudah didapat, serta memiliki harga yang sangat terjangkau.…”

Coconut fiber is an alternative material to replace metal. Coconut fiber was chosen because it is easy and widely found in Indonesia and is easily decomposed naturally. Even though its strength is much lower than metal, coconut fiber can be used to make objects that do not require a lot of strength, one of which is drones. In this research, coconut fiber composites were made and tensile tested to determine their strength for use as a frame for small surveillance drones. The composite is made by mixing coconut fiber mat (as fiber) and Unsaturated Polyester (as resin) using the hand lay-up method. Coconut fiber composites are tested according to ASTM D-638 standards. Based on the tensile test results in this research, it was found that the coconut fiber composite had a tensile strength of 18 MPa. Then this number is used as a benchmark in determining the size of the surveillance drone frame to be designed. Based on the results of the calculations carried out, it was found that the thickness required for a drone frame made from coconut fiber is 4 mm

Palm and coconut fibers are able to accommodate different water, have good insulation of temperature and sound. The combination of palm and coconut fibers as a reinforcement of natural fiber composites is influenced by the characteristic thickness of the constituent materials. This study aimed at describing the effect of thickness on various variations of the composition of palm and coconut fiber as a reinforcement of natural fiber composites. Natural fiber composites were made by hand lay-up methods. The comparison of fibers and matrices was 40% and 60%. The variation in the composition of the weight of coconut fibers in the fiber was 20%, 40%, 60%, 80%. The fiber used a chopped fiber model with a length of 3 cm. Thick development data analyzed descriptively to refer to SNI 03-02105-2006. The density of natural fiber composites in all variations in the composition of the weight of coconut fibers in the fiber was in the range of values of 1.0893 to 1.0956 gr / cm3. Soaking with water for 24 hours showed that the composite board had a thick development of 2% to 5.9%. Composite of natural fiber with the composition of 80% fibers and 20% coconut fibers experienced the largest thickness development which was 0.65 mm.
